DERAIL.

Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed. September 5, 1914. Serial No. 860,355.

To all whom it may concern Be it known that I, STANLEY W. HAYES, acitizen of the United States, residing at Richmond, in the county of-\Vayne, State of Indiana, have invented thefollowingdescribedImprovements in Derails.

The improvement involves certain principles of construction andoperation capable of application to derails in various ways to improvethe utility thereof, and includes a method and means of assembling andrelating the several parts of derails whereby they can be operated byhand of by foot in one or both directions, and whereby they may bereadily and automatically latched and lockedin one or both positions,and whereby the character of movement of the derail block toward andfrom the railmay be made to suit various requirements, whether operatedby foot or otherwise, and also certain other features of advantage andimprovement, all as hereinafter set forth and claimed.

In the drawings, Figures 1 and 2 are top plans of one form of thisinvention, illustrating the features above referred to, Fig. 1 showingthe derail open and Fig. 2 closed; Fig. 3 is a longitudinal section ofthe closed derail, with parts in elevation; Fig.4 a rear view of thesame in the open position; Fig. 5 a side elevation of the open derail;Fig. 6 a section at the latch, the derail being open; and Fig. 7 thesame with the derail closed.

The derail comprises a base with flanges l on either side, by means ofwhich it may be spiked to two adjacent ties. Such portion of the base asdepends below the flanges occupies the space between the ties, and theforward or rail end of the base turns upwardly so as to abut against theweb of the rail when in'proper position on the road-bed. The uprightside wall portions 2 are joined by a roof 3 and braced and reinforced bya couple of angle ribs 4. as well as by a rear wall 5. The basestructure is desirably made or cast in a single piece, although it mightbe otherwise, and within its interior are formed the various bearingsurfaces by which the moving derailing member is supported and guided.The derailing member is preferably also, but not necessarily, asinglepiece or casting, and comprises a derail-block 6 carried at theforward end of the main or body portion, which'latter is confined withinthe base and provided with a set of bearing surwall and roof portions,suitably rib-braced in the interior, and its forward portion, marked 7,is considerably wider than its rearor tail portion, marked 8. The widerpart substantially fills the space between the side walls 2 of thederail, while the narrow tail portion 8 is adapted to be guided in andproject through the relatively small opening in the rear wall 5.Moreover the wide and narrow parts of the derailing member are disposedat an angle to each other and at about their point of junction, that is'to say, in the region of the apex of the angle, the said member has itsforward bearings. In the present case, this bearing consists of a pairof opposite studs 9, each normally resting on a bearing surface 10 onthe base and adapted also to engage an upper inclined bearing surface 11immediately above the said surface 10. The two surfaces 10 and 11constitute the horizontal walls of a curved groove formed in each sidewall of the base or standard, and are open at their forward end topermit the introduction of the studs therein, the rear end of thegrooves being open downwardly through a hole 12, this latter holeserving to make the grooves self-cleaning of dirt.

' The derailing member is adapted to tilt or rock on the bearing studs 9within the limits prescribed by the arrangement of the other parts, andalso and coincidently to slide in the groove toward or from the de rail,the curvature of the said groove serving to impart a curvilineardirection, or upand-over component, to the path of movement of thederailing member as a whole. Such curvature may be greater or less, asdesired and as will be evident, and according to the disposition of thegrooves. At its rear end the derailing member is adapted to be supportedalternately on the lower and upper margins of the opening in the rearwall 5. The lower surface of said opening, marked 13 (Fig. 3) is adaptedto be engaged by the under surface 14 of the body part 8, that is tosay, by the bottom edges of the fulcrum bearing, vertical or downwardpres sure on the projecting rear end of the derailing member will forcethe studs 9 upwardly against the surface 11 above described, and byvirtue of the inclination or 'curvature of that surface will cause thestuds to move forwardly in their grooves, thereby moving the derailblock toward the rail. Such movement takes place in a gradual upwarddirection which continues until near the end of the stroke, when, byvirtue of the decreasing leverage and the change of direction of thegrooves or surface 11, the derail block 6 drops upon the rail, assumingthe position indicated in Fig. 5. In this position the shoulder portions15 depending below the derail block,'occupy the thrustseat formed by thespace between the extended side walls 2 at the rail end of the standard,dropping into such seat from the top of their path of movement. Thethrust-seat serves to prevent movement of the derail blocklongitudinally of the rail. The shoulders 15 are constituted by the sidewalls of V the body part 7, and are rounded, as indicated, so that theymay, if desired, ride on the complementary base shoulders 16 when movinginto the seat. These base shoulders 16 project inwardly from the sidewalls 2 far enough to accommodate the support of the shoulders 15, butso as to leave an open space between them- (see Fig. 2), through whichforeign objects may pass through the base without remaining to obstruct.operation of thedevice. The perforated lug 31 between and slightlyforward of the bearingstuds 9 is a connection lug formed as a downwardextension of one of the internal bracing-ribs in the interior of thebody part 7. The derail may be connected with a pipeline or target-standby means of this lug,

if such connection is desired.

.The upper surface 17 of the rear opening in the base structure isadapted to be engaged by the upper edge of a fin 18, extendmg from apoint near the studs 9 to a point near the end of the derailing member,and the function of such engagement is to limit and control the extentof downward tilting of the derail block end of the member, this endbeing, of course, much heavier than the narrow tail end. The shape ofthe fin may obviously be made to permit greater or less tiltingmovement, although it will be evident that a change of the angle betweenthe body parts 7 and 8 can also be resorted to for controlling thetilting action.

lVith the derail in the open position of Fig. 5, a wedge or cam surface19 formed on the under side of the tailend of the derailing member isdirectly over a corre spending wedge'surface or cam 20 on' the base, andby tilting the rear end of the member downwardly, as by pressing upon itwith the foot, the said surfaces may be brought into engagement, andsuch engagement will draw or force the derail block from the railsufficiently to start it overthe incline 21 of the groove (Fig. 8) orover the incline of the base shoulders 16, as the case may be, andthereupon gravity impels the member the rest of the way back to itsclosed position. During such movement, the rear end. of the derailingmember rises corresponding to the depression of the derailblock. 7

From the foregoing it will be evident that the arrangement of bearingsurfaces between the derailing member and its structure coiiperate toimpart movement of the former transversely of the rail and in eitherdirection, and that both such .movements are or may be the result ofpressure or force applied, in both instances, in a vertical direction ora direction transverse to the movement toward the rail. The device maythus be readily operated by the foot, as by stepping upon the foot-hold22 provided for the purpose. -It may also be operated. by hand, ifdesired, and for this purpose the hand-hole -23is formed in the roofwall of the hollow-body part 7. l/Vhen thus operated the upward pull onthe forward end results in the same effect as downward pressure on therear end and inas much as it is natural to pull upwardly when performingthe manual operation, theblock moves with so much "the greater facility.

Eithermethod of. operation may thus be used and one or morevcombinations of co.- operatmg surfaces may be employed to provide one ormore of the movements described, it being. evident that the retractive'surfaces operateindependently ofthe advancing surfaces and that eithermay hence be used to the exclusion of the other. The read end of thederailing member moves downwardly in the beginning of the stroke in eachdirection and the derail may thus be locked closed oropen by means of alatch 24: adapted to obstruct such downward movement. The latch-24c ispivoted in a frame forming part of the base structure and is adapted toswing by the effect of gravity under the rear part 8 Inthe open 7position it hooks under the extreme rear end, and in the closed positionunder the ledge 26 formed by a recess cast in the side wall. Inintermediate positions it is held from swinging into locking position bythe engagement of its nose with the side of the derailing member.Additional means are. provided to hold the latch withdrawn,

applied to the foot or hand hold, thereby providing but one part to beoperated at a time. To this end the latch 24: is loosely pivoted at itspin in the frame 25 and its hub carries a spur 27. By raising the latch,which may be done with the foot or hand, the spur is caused toride overeither one of two corresponding spurs 28, 29 according as the derail isin one position or the other. These spurs are formed on the back of thederailing member and hold the latch in its withdrawn position untilmovement of the derailing member withdraws the spurs, whereupon the noseof the latch will then rest against and ride over the side of thederailing member ready to hook under the same again at the end of thestroke. The latch has a handle 30 by which it is readily engaged by thehand or foot and directly above the handle, when the latch is in itslocking position, a hole 32 is drilled through the corner of the rib 4so that a padlock looped therein will lock the latch and derail ineither closed or open position.- 7

From the foregoing, it will be evident to those skilled in this art thatthe device described is susceptible of various modifications and changein the proportions of its parts, and it will be understood that thefollowing claims are intended to cover all such modifications, changesand also reversals of arrangement within the scope of the invention, theprinciples of which have now been clearly set forth.
